The heat sealing gasket on your EGG is designed to last for years under normal operating conditions. However, if the gasket does show signs of excessive wear or deterioration, it can be easily replaced using the Big Green Egg Gasket Kit, which is easy to use and self-adhesive. The new design increases temperature efficiency and can stand temperatures up to approximately 500 degrees.
